When the body of a talented photographer is found on the rocks beneath the ruins of Dunstanburgh Castle, DCI Ryan and his team of detectives immediately suspect the worst. But, since none of their potential suspects seems to have a motive, the case runs cold.

Then, when another body is found dead on a lonely stretch of road near Hadrian’s Wall and their only suspect has an airtight alibi, the team are faced with another crime without a perpetrator. With the number of unexplained deaths in the area increasing rapidly and only a series of coincidences to work from, Ryan and his team must find the invisible link between them to crack the case—before it’s too late. Can Ryan solve his most dangerous case yet? Murder and mystery are peppered with romance and humour in this fast-paced crime whodunnit, set amidst the spectacular Northumbrian landscape.
